Concomitant psychiatric disorders in people with diabetes affect morbidity and mortality. We aimed to study psychiatric morbidity in people with diabetes and the general population using administrative health care data in Stockholm County. The study population included all living persons who resided in Stockholm County, Sweden, on January 1, 2011 (N=2,058,408). Subjects with a diagnosis of diabetes were identified with data from all consultations in primary health care, specialist outpatient care and inpatient care during the time span 2009-2013. As outcome, information was obtained on all consultations due to any psychiatric diagnosis as well as, specifically, schizophrenia, bipolar disorders, depression, and anxiety disorders, in 2011-2013. Analyses were performed by age group and gender. Age-adjusted odds ratios (ORs) with 95% confidence intervals (95% CI) for women and men with diabetes, using individuals without diabetes as referents, were calculated. Age-adjusted OR for all psychiatric diagnoses among people with diabetes was 1.296 (95% CI 1.267-1.326) for women and 1.399 (95% CI 1.368-1.432) for men. The greatest excess risk was found for schizophrenia, with OR 3.439 (95% CI 3.057-3.868) in women and 2.787 (95% CI 2.514-3.089) in men, with ORs between 1.276 (95% CI 1.227-1.327) and 1.714 (95% CI 1.540-1.905) for the remaining diagnoses. The prevalence of psychiatric disorders is elevated in people with diabetes, which calls for preventive action to be taken to minimize suffering and costs to society.
